St Ives Gold Mine Technical Short Form Report 31 December 2012 1 St Ives Gold Mine Technical Short Form Report 31 December 2012 1. Overview The St Ives Gold Mining Company (Proprietary) Limited (St Ives) Salient featuru ess is wholly owned by Gold Fields Limited and is situated some 80 kilometres south of Kalgoorlie. The St Ives operations are X Mineral Resources at 4.7 Moz. conducted within mining tenements comprising 277 mining X Mineral Reserves at 2.2 Moz. titles (54,749 hectares), three mineral titles (364 hectares), 13 exploration licences (27,192 hectares), 22 prospecting X High-cost heap leach operation closed. licences (2,700 hectares) and 19 miscellaneous licences X Highly prospective tenement delivered new (14,500 hectares) for a total area of approximately exploration camp and Mineral Resources at 99,594 hectares. St Ives has security of tenure for all current Invincible. mining titles and exploration licences that contribute to the X Mineral Reserves. Neptune Mineral Resources and Mineral Reserves continue to grow; detailed technical St Ives represents a solid base for growth in Australia and is an planning initiated. important contributor to the Gold Fields’ vision of being “the X Hamlet well on track to achieve full production global leader in sustainable gold mining” with a target contribution in 2013. from the Australasia Region of approximately 0.7 Moz per annum X Life of Mine extends to 2018 (6 years). by 2015. St Ives currently operates four underground mines accessed via declines and several open pits, a centralised administrative office, an engineering workshop and CIP processing plant. Declared Mineral Resources at St Ives decreased by 490 koz primarily due to depletion and closure of the Leviathan, Formidable, Dianna, Minotaur and Britannia Footwall pits during 2012. The Mineral Reserves, inclusive of a depletion of 490 koz since December 2011, declined to 2.2 Moz (2.8 Moz at December 2011). Changes to Mineral Reserves from December 2011 were dominated by limited discoveries at Neptune and Cave Rocks, with nominal additions at Hamlet and Athena. Continued exploration success and increased drilling of the mine’s extensive greenfields project pipeline has led to further discoveries at the Incredible deposit, which now extends over 600 metres on-strike and is still open to the north. Further work is planned in 2013 to grow the deposit’s continuity and resource confidence. The St Ives Life of Mine (LoM) has been maintained at six years to 2018. This Technical Short Form Report reflects the latest LoM plan, coupled with an updated Mineral Resource and Mineral Reserve statement as at 31 December 2012. All Mineral Resource and Mineral Reserve figures reported are managed unless otherwise stated and Mineral Resources are inclusive of Mineral Reserves.

  • Autonomous Exploration and Mapping of Abandoned Mines
    Autonomous Exploration and Mapping of Abandoned Mines Sebastian Thrun2, Scott Thayer1, William Whittaker1, Christopher Baker1 Wolfram Burgard3, David Ferguson1, Dirk Hahnel¨ 3, Michael Montemerlo2, Aaron Morris1, Zachary Omohundro1, Charlie Reverte1, Warren Whittaker1 1 Robotics Institute, Carnegie Mellon University, Pittsburgh, PA 2 Computer Science Department, Stanford University, Stanford, CA 3 Computer Science Department, University of Freiburg, Freiburg, Germany Abstract Abandoned mines pose significant threats to society, yet a large fraction of them lack ac- curate maps. This article discusses the software architecture of an autonomous robotic system designed to explore and map abandoned mines. We have built a robot capable of au- tonomously exploring abandoned mines. A new set of software tools is presented, enabling robots to acquire maps of unprecedented size and accuracy. On May 30, 2003, our robot “Groundhog” successfully explored and mapped a main corridor of the abandoned Mathies mine near Courtney, PA. The article also discusses some of the challenges that arise in the subterraneans environments, and some the difficulties of building truly autonomous robots. 1 Introduction In recent years, the quest to find and explore new, unexplored terrain has led to the deploy- ment of more and more sophisticated robotic systems, designed to traverse increasingly remote locations. Robotic systems have successfully explored volcanoes [5], searched meteorites in Antarctica [1, 44], traversed deserts [3], explored and mapped the sea bed [12], even explored other planets [26]. This article presents a robot system designed to explore spaces much closer to us: abandoned underground mines. According to a recent survey [6], “tens of thousands, perhaps even hundreds of thousands, of abandoned mines exist today in the United States.

  • Treatment of Disused Lead Mine Shafts
    Cover: The many surviving lead mining shafts and sites of Derbyshire and the Peak District feature a wide variety of conservation interests. As shown here (top left - David Webb) shafts provide access for cave exploration, though a safe method of access may need to be provided as shown here (bottom right – Ian Gates). On the surface there is archaeological interest in the waste hillocks and other structure (top right John Humble) and specialist plant communities survive that include metal tolerant species such as this spring sandwort (bottom left – John Humble). Shafts were often lined with a dry stone walling known as ginging (centre right – David Webb) which can be vulnerable to damage when they are capped.

  • What's the Deal with Tintina Resources and Its Proposed Black
    What’s the Deal With Tintina Resources and its Proposed Black Butte Mine? Montana Trout Unlimited July 2014 Who is Tintina Resources? Tintina is a little-known, fairly new Vancouver, Canada, mine exploration company. It has never operated a mine. Four of its six board members are Canadians. The other two board members are Americans who represent large hedge funds that together own more than half the shares in the company. The company’s two main front people are Meagher County natives -- its vice president of exploration, and its public relations staffer. Though the company touts its relationship with both as proof it cares about the local environment, neither individual is important enough to be on the board of directors. Tintina’s cash and assets, to this point, are fairly limited. It will probably need a large partner to operate a mine. Or, it will sell its interests to an established mining company once it has added value by further characterizing its potential ore reserves, or by obtaining mining permits. In June, an Australian copper mining company was in Montana investigating potential purchase of the Black Butte Mine project. What is Tintina Proposing? Tintina proposes to construct a large underground mine primarily for copper on private property near main Sheep Creek and its South Fork, in the upper Smith River drainage. Though it has not submitted specific mine plans to date, conceptual plans the company has been using to sell the project is that its footprint – tailings (waste material), waste rock, crushing facilities, discharge areas, potential water treatment plant, roads, etc., could take up a considerable amount of the 7,500 private acres it is leasing.

    Dr Chris Baker April 2019 LEFROY EXPLORATION LTD LEX:AU, $0.20. Market cap A$16.2 m Air core results confirm two gold trends under Lake Lefroy Recent site visit confirms prospectivity of other LEX targets - Gold Fields has released its first tranche of drill results from air core drilling on the LEX-JV, east of the world class St Ives gold project. - Results confirm the existence of two gold-anomalous trends beneath Lake Lefroy. - The immediate target is a 3km zone along the inferred Woolibar Fault centred on the Zanex prospect. - The Eastern Shoreline Trend has identified a +3km zone of gold anomalism. - Both trends are worthy of follow-up with RC or diamond drilling, likely to happen in 2H19 - LEX will continue to focus on Lucky Strike and other 100%-owned projects to the east of Lake Lefroy. A 2000m RC/diamond programme is currently underway. - LEX is a very inexpensive WA exploration play strongly leveraged to GFI’s aggressive exploration programme on Lake Lefroy, and to exploration within its 100%-owned tenements in the Mt Monger area. Expect plenty of exploration news over the rest of the year. Warm colours (red/purple) signify higher gold grades. Source: From ASX release 15 April 2019 LEFROY EXPLORATION (ASX: LEX) | Research report FIRST EXPLORATION RESULTS FROM THE GOLD FIELDS JOINT VENTURE LEX holds tenements covering nearly 600km2 to the east of and adjoining Gold Fields’s 100%-owned St Ives gold mine and were recently joint ventured with Gold Fields (GFI). As discussed in more detail below, GFI can earn up to 70% of LEX’s western Lake Lefroy tenements with the expenditure of A$25m.
